A leading researcher at ETH Zurich warns that Switzerland faces a critically important risk of a major power outage, stating it’s not a matter of “if,” but “when.” Leonard Schliesser, a senior researcher specializing in risk and resilience at the center for Security Studies (CSS) of ETH Zurich, recently published an analysis highlighting the potential for widespread and long-lasting blackouts in Europe.
Schliesser’s research focuses on protecting critical infrastructure and preparing for low-probability, high-impact events like catastrophic blackouts, according to the university.
His recent analysis underscores the perhaps devastating societal impact of large-scale, extended power outages. “Being unprepared is negligent as the blackout brings a catastrophic potential,” Schliesser noted in his report.
Iberian Peninsula Blackout: A Warning Sign?
Schliesser addressed a recent power failure affecting parts of Spain,Portugal,and France,offering insights into the event’s causes and implications for Switzerland.
Question: The recent blackout in Spain and Portugal: Did it surprise you?
Schliesser: “Such an event always occurs unexpectedly, so I was surprised. I was very aware that it can happen.”
Question: Are such events becoming more frequent?
Schliesser: “We speak of events of great rarity with great effect…Risk analyzes are therefore more about scenarios than intervals of occurence.”
Question: In 2024, you wrote that power failures could quickly take on a cascade of “continental excavation” in today’s electricity.
Schliesser: “Fortunately, this has not arrived because the network’s defense mechanisms works in good time, especially in france and isolated the blackout on the Iberian peninsula.”
Question: What are these defense mechanisms?
Schliesser: “Defense sounds a bit militaristic, of course. But ultimately you can imagine it like the fuse box at home. In the event of an overload, the components of the power grid separate – i.e.transformers, generators or consumers – from the network.”
Question: Could Switzerland feel the effects of such a blackout?
Schliesser: “A blackout of this order of magnitude results in a frequency drop in the rest of Europe. However, this moved in an area in which one could counteract regular measures.”
Question: Specifically, this means that a few pumped storage power plants or other reserve power plants have drained water at short notice and fed electricity into the network.
Schliesser: “Exactly. This is about the short -term provision of control energy. Pump memory are classic suppliers who can deliver energy within seconds.”
Switzerland’s Vulnerability
Question: Is a scenario like in Spain also conceivable in Switzerland?
Schliesser: “The question is not at all whether, but when. In 2003 ther was already a major power failure in Italy, which was also affected by Switzerland… It is known from behavioral psychology that this leads to a distorted perception: we hardly expect that something like this can suddenly drop out.”
Question: What role does the transformation play to renewable?
Schliesser: “From a scientific point of view, this is difficult to assess because, as I said, the statistical basis is missing. In general, however, it can be said that many European countries reduce their conventional power plants… The risk of a blackout is a bit larger. In the future, if you learn to deal with it, this probability will decrease again.”
Question: In Switzerland, there was a primary talk of electricity deficiency in the past few years. This event has nothing to do with this in Spain.
Schliesser: “No.A power deficiency extends over a longer period of time and means to be able to cover only part of the need for energy. The phenomenon is very well known, especially in South Africa. With a blackout, an entire network is powerless.”
Question: How do you assess Switzerland’s resistance, should such a large power failure occur here too?
Schliesser: “I think a lot has happened because of the threat of a electricity deficiency… Switzerland is sensitized. And the contry is also well positioned: Swissgrid is one of the best distribution network operators in Europe.”
Question: In Spain, a famous department store is said to have bridged the power failure with generators on the roof: Customers, reports, were able to continue shopping. Is that the future: for yourself?
Schliesser: “I don’t really want to answer this question because it is political… It is important that the central pillar of society also works in such a case.”
Civil Preparedness: A Key to Resilience
Question: You write that a society is only nine meals away from the anarchy. That sounds dramatic at first.
Schliesser: “Empirical studies show that a normal household provides for about 72 hours. After that it gets tight… If you don’t know what will happen, the situation can quickly become dramatic.”
Question: What would you advise?
Schliesser: “To make up for! Individual emergency provision is actually a civil obligation,or should it be at least.”
Switzerland Faces “Mega Blackout” Risk: An Expert Q&A
Are you concerned about the possibility of a major power outage affecting Switzerland,or even Europe? This article provides an in-depth Q&A with Leonard Schliesser,a senior researcher at ETH Zurich specializing in risk and resilience,to shed light on this critical topic. schliessers research focuses on the potential for widespread and long-lasting blackouts and what we can do to prepare.
The Threat of a “Mega Blackout”: An Overview
Schliesser’s research highlights that it’s not a matter of “if” but “when” when considering a significant power outage. Let’s delve into the specifics of this potential threat and what it may mean for Switzerland and its citizens.
Understanding the Iberian Peninsula Blackout
To understand the risks, it’s helpful to consider recent events. Let’s start by examining the recent blackout in parts of Spain, Portugal, and France.
Q: The recent blackout in Spain and portugal: Did it surprise you?
A: “such an event always occurs unexpectedly, so I was surprised.I was very aware that it can happen.”
Q: Are such events becoming more frequent?
A: “We speak of events of great rarity with great effect…Risk analyzes are therefore more about scenarios than intervals of occurence.”
Q: In 2024, you wrote that power failures could quickly take on a cascade of “continental excavation” in today’s electricity. What does this mean?
A: “Fortunately, this has not arrived because the network’s defense mechanisms works in good time, especially in France, and isolated the blackout on the Iberian peninsula.”
Q: What are these defense mechanisms?
A: “Defense sounds a bit militaristic,of course. But ultimately you can imagine it like the fuse box at home. In the event of an overload, the components of the power grid separate – i.e.transformers, generators or consumers – from the network.”
Q: Could Switzerland feel the effects of such a blackout?
A: “A blackout of this order of magnitude results in a frequency drop in the rest of Europe. However, this moved in an area in which one could counteract regular measures.”
Q: Specifically, this means that a few pumped storage power plants or othre reserve power plants have drained water at short notice and fed electricity into the network.
A: ”Exactly. This is about the short-term provision of control energy. Pump memories are classic suppliers who can deliver energy within seconds.”
Switzerland’s Vulnerability to Power Outages
the Iberian Peninsula blackout provides context. Now, let’s focus on Switzerland’s specific risks.
